I can’t be the only one who’s fallen victim to an eye-watering quote from their dentist for a teeth whitening session. I’m getting married in a few months’ time, so I decided to save my cash (and my already large wedding budget) and stick to at-home teeth whitening kits to get me a sparkling smile for my big day.

That’s where Smilie comes in.

Natalie Smith was also “completely shocked” at how expensive an in-chair teeth whitening session was going to cost her.

After doing some research and joining an “incredible partnership” with dentist Dr. Daniel Tankard and her partner Peter Wiltshire, the trio spent about 18 months in development to create the perfect at-home kit.

“We worked on refining the formulation and the actual device, made some changes based on consumer feedback, which was key to our initial success … lots of friends and family were so excited and wanted to try it for themselves.”

The award-winning Smilie Boost Teeth Whitening Kit has an extremely low refund rate according to Natalie, and its success shows no signs of slowing down.

So I decided to test the kit for myself – that also happens to be on sale for 60 per cent off right now – and the results were surprising.

OUR REVIEW OF THE SMILIE TEETH WHITENING KIT

Tried and Tested by Marina Tatas, news.com.au Shopping Writer

Bit of background, whitening my teeth is an crucial step in my beauty routine.

I always use a whitening toothpaste, so I wasn’t expecting a drastic change from using this highly-rated whitening kit. I did, however, have some discolouration around my canine teeth, and I was keen to see if the Smilie Teeth Whitening Kit could fix this.

Oh, and probably thanks to my daily whitening toothpaste, my teeth can also feel quite sensitive.

Luckily, this is one of the problems that Smilie aims to correct for at-home teeth whitening kits.

“Potential sensitivity can make people really nervous, so our formula actually contains desensitisers and soothers. It’s kind of a balancing act between getting the right amount of the active ingredient to actually work but then also ensuring it doesn’t cause pain and sensitivity,” Natalie explains.

“We didn’t want to cause any pain and we’ve never received a single complaint about that. It’s something we stand by and it’s how we’re different to other products on the market.”

Here's a before and after of my teeth after trying the Smilie Boost Teeth Whitening Kit for a week straight.

So how do I rate the Smilie Teeth Whitening Kit? It’s safe to say I am genuinely impressed.

Like I mentioned, I wasn’t expecting a drastic change, but I have surprisingly noticed the Smilie Teeth Whitening Kit has made my smile look whiter and brighter after using it every single day for just a week.

The stains on my canine teeth that I mentioned earlier have started to clear, and I’m super happy with the overall results.

How did the sensitivity go? Well to be honest, I did experience some, but that could also be because they were already sensitive to start with – so take from that what you will.

I love how easy the Smilie Kit is to use. You apply the gel all over your teeth from the pre-filled whitening pens and then stick the LED device into your mouth and hit the button to turn on the blue light. It’s pre-timed so it will automatically turn off when the 16 minutes are up. Once I’m done, I rinse the mouth guards with warm water and leave them to air dry.

The Smilie Boost Teeth Whitening Kit comes with a handy colour guide to compare your results.

It also comes with a USB-charging cable (which I’m yet to use after seven uses) and a handy teeth shade guide so you can compare your progress. According to the guide, I started around a three, and I feel as if my teeth are looking pretty close to a one.


WHAT MAKES SMILIE DIFFERENT FROM OTHER ORAL CARE BRANDS?

Natalie describes how “it’s a very competitive space now, but we have a very loyal customer base. We often have people who will buy the initial starter kit and then come back and buy it for someone else in their family.”

“Our biggest differentiator is that our formulations are developed, used and trusted by dentists, we are also stocked in dentists throughout the country,” Natalie told news.com.au checkout.

I’ve actually tried a few different teeth whitening kits in the past, and I truly feel this one gave me the best results in the shortest amount of time.
